Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a door lock detection device that can easily and accurately detect the locked state of a sliding door that is locked and unlocked using a crescent lock.

2. Prior Art This type of conventional door lock detection device is equipped with a monthly magnet and a reed switch on the window frame side in a position opposite to the magnet. A configuration that detects whether the door is closed by using the fact that the reed switch is turned off when the door is open is common and widely used. However, this configuration has the disadvantage that although it is possible to detect whether the window is open or closed, it is not possible to detect whether the window is locked or unlocked. Therefore, in view of this drawback, Japanese Utility Model Application Publication No. 58-93154 utilizes the fact that the engaging body and the engaged body of the crescent lock engage when locked.
A door lock detection device has been devised in which an engaging body and an engaged body are used as contact points of a switch.

Problems to be Solved by the Invention However, with the above configuration, when the window is closed, 2
An elastic tongue piece must be installed at the position where the window frames of two sliding doors face each other, and the window frames of the two doors must be electrically connected, or the engaging body must be insulated from the window frame to which it is attached. There were issues such as reliability and structural difficulties.

The present invention has been made to solve such conventional problems, and an object of the present invention is to provide a reliable door lock detection device with a simple configuration.

Means for Solving the Problems In order to solve the above problems, the door lock detection device of the present invention detects the open/closed state of two doors constituting a sliding door that is locked and unlocked by a crescent lock. The door lock detection means is provided with a window opening/closing detection means and a lever rotation detection means for detecting the rotation angle of the locking/unlocking lever of the crescent lock.

Further, when the window opening/closing detection means indicates the closed state of the sliding door and the lever rotation angle of the lever rotation detection means indicates the angle at the time of locking, the locking determination means determines that the crescent lock is in the locked state. It was established.

Further, the first window opening/closing detection means is provided with a light emitting element and a light receiving element on one door constituting the sliding door, and on the other door when the two doors are in a closed positional relationship, from the light emitting element to the other door. The device has a configuration in which a reflecting plate is provided to reflect the emitted light and allow the light to enter the light receiving element, thereby detecting whether or not the window is opened or closed.

The second window opening/closing detection means is provided with a magnetism generating element in one of the sliding doors, and a magnetism generating element is provided in the other door when the two doors are in a closed positional relationship. This device is configured to detect opening/closing of a window by arranging a magnetic detection element to detect magnetism.

Further, the third window opening/closing detection means is provided with an inductance element and an inductance measuring means for measuring the inductance on one door constituting the sliding door, and a positional relationship in which the two doors are closed on the other door. In this case, a magnetic material that changes the inductance value of the inductance element is disposed to detect opening/closing of the window.

Further, the fourth window opening/closing detection means includes a microswitch on one door of the sliding door, and an actuator of the microswitch on the other door when the two doors are in a closed position. This device is configured to detect opening/closing of a window by disposing a convex operating body for energizing a push contact.

The first lever rotation detection means includes a lever mechanism in which the actuator of the microswitch is energized when the crescent locking lever is at the locking rotation angle, and is released when the locking rotation angle is at the unlocking rotation angle. It is equipped with a configuration that performs angle detection.

Further, the second lever rotation detection means detection means includes a light emitting element,
a light receiving element for receiving the light emitted from the light emitting element;
It has a shutter mechanism for blocking the optical path between the light emitting element and the light receiving element, and this shutter mechanism rotates in conjunction with the rotation of the locking/unlocking lever of the crescent lock, and the lever rotates at the locking rotation angle. In this embodiment, the rotation angle of the lever is detected only when the optical path is interrupted.

Further, the third lever rotation detection means includes a light emitting element, a light receiving element, and a reflecting plate for reflecting the light emitted from the light emitting element and making it enter the light receiving element, and this reflecting plate is used for the crescent lock. A configuration in which the rotation angle of the lever is detected by forming an optical path between the light emitting element and the reflection selective light receiving element only when the lever is at the locking rotation angle. It is equipped with the following.

The fourth lever rotation detection means includes a magnetic generation element and a magnetic detection element, and the magnetic generation element rotates in conjunction with the rotation of the locking/unlocking lever of the crescent lock, so that the lever is locked. The rotation angle of the lever is detected by a configuration that allows the lever to approach the magnetic detection element and detect the generated magnetism only when the lever is at the rotation angle.

Function: With the above-described configuration, the present invention can not only detect the open/closed state of the sliding door, but also detect the closed state of the window in combination with the detection of the rotation angle of the locking/unlocking lever of the crescent lock.

In the case of the first window opening/closing detection means, when the sliding doors are closed, the light emitted from the light emitting element installed on one door is reflected by the reflective plate installed on the other door and returns to the original state. An optical path is formed that enters the light receiving element provided in the door, but when the door is open, the optical path is not formed, so it is possible to detect whether the window is open or closed.

In the case of the second window opening/closing detection means, when the sliding doors are closed, the magnetism emitted from the magnetic generation element provided on one door is detected by the magnetic detection element provided on the other door. However, since it is not detected when the window is open, it is possible to detect whether the window is open or closed.

In the case of the third window opening/closing detection means, when the sliding doors are closed, the inductance value of the inductance element provided on one door becomes a larger value due to the influence of the magnetic material provided on the other door. However, when the window is open, the magnetic material has no effect, so the value is smaller, so it is possible to detect whether the window is open or closed.

In the case of the fourth window opening/closing detection means, when the sliding doors are closed, the actuator of the microswitch provided on one door is pushed by the convex operation piece provided on the other door, and the contact is activated. However, since the contacts are not energized when the door is open, it is possible to detect whether the window is open or closed.

In the case of the first lever rotation detection means, when the lock/unlock lever of the crescent ffl is at the locking rotation angle, the actuator of the microswitch is energized by the Leno<- mechanism, and when it is at the unlocking rotation angle, it is released. , the rotational state of the lock/unlock lever can be detected.

In the case of the second lever rotation detection means, when the locking/unlocking lever of the crescent lock is at the locking rotation angle, the optical path between the light emitting element and the light receiving element is blocked by the shutter mechanism; In some cases, the rotation state of the lock/unlock lever can be detected because it is not shut off.

In the case of the third lever rotation detection means, when the locking/unlocking lever of the crescent lock is at the locking rotation angle, the reflection plate rotates to a predetermined position in conjunction with the lever, and the light path between the light emitting element reflection plate and the light receiving element is However, since it is not formed when the locking lever is at the unlocking rotation angle, it is possible to detect the rotational state of the locking/unlocking lever.

In the case of the fourth lever rotation detection means, when the locking/unlocking lever of the crescent lock is at the locking rotation angle, the magnetism generating element approaches the magnetic detecting element, making it possible to detect magnetism.
At the unlocking rotation angle, magnetism cannot be detected, so the rotational state of the locking/unlocking lever can be detected.
